CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 461,198, dated October13, 1891.

Application filed July 2,1891. Serial No. 398,215. (No model.)

To (tZZ whom it may concern:

Be it known that I, FRED H. HENRY, of \Vakefield, in the county ofMiddlesex and State of Massachusetts, have invented new and usefulImprovements in Car-Seats, of which the following is a specification.

This invention relates to that class of carseats in which the backswings over the seat from one side edge to the other without turnin gover, said back being upholstered on both sides for the purpose, and inwhich the swinging of the back from one edge to the other of the seatcauses the cushion to move and tilt so as to be in proper position forthe occupant.

The invention consists in the novel construction and combination ofparts below described, whereby this style of car-seat is made moreefficient and positive in its operation and atthe same time simple andnot easily put out of repair.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is a cross vertical section of a carseatembodying my invention. Fig. 2 is a similar section with theseat-back-swung to the opposite side. Fig. 3 is an enlarged verticalsection and elevation, the section being taken longitudinally throughthe seat-arm when the seat-back is in a nearly-vertical position, aportion of said seat-arm being represented as broken out. Fig. 4 is asection on line 00, Fig. 3. Fig. 5 is a section on line y, Fig. 2. Fig.6 is an enlarged perspective showing certain parts in detail. Fig. 7 isa detail in perspectiveshowing one of the slides or rockers and aportion of the frame of one of the cushions adapted to fit therein. Fig.8 is aview of the same, showing a slight modification.

The back and seat are shown in broken lines in Figs. 1, 2, and 5.

A represents the uprights, secured to the floor and supporting the seat.B is the connecting-rail, and C the foot-rails, all constructedsubstantially as usual.

D D are the end rails or cross-pieces of the seat-frame, supported inthe ordinary manner by the uprights A and supporting the posts D, whichsupportthe seat-arms E.

F F are the end irons of the back F. Pivotally secured at f to theseends F are the upper ends of the swinging arms H, which are fulcrumednear their lower ends at g to the end rails D. -Each of these swingingarms H is provided with a longitudinalslot h, and the link I is pivotedat one end ate to the end iron F and at the other end is provided with apin or projection J, Figs. 4 and 5,which lies in the sloth and which isprovided atits outer end with the tooth-segment J, Figs. 3, 4, and 5.

K is a horizontal plate or track secured to the inner side of theseat-arm, extendingwfor nearly the length thereof and provided with thelongitudinal groove K. The pin or neck J is made long enough to extendnot only through the sloth, but through the slot or groove K, in whichit is held by the tooths'egment J, which lies within the slot behind theshoulders K, Figs. 3 and 4. The track is gouged out at Z, so that thetooth-segment can be withdrawn by turning it, if desired,

without removing the track from the seatarm.

Then the seat-back F is desired to be swung from one side of the seat tothe other, one of the arms H is grasped by the handle H, Fig. 5, and thearms swing on their pivotsg, their upper pivoted ends carrying the upperportion of the seat-back, while the links I, sliding in the slots h bythe action of the pin J in the grooved track K, carry the lower portionof the seat-back and, describing a crank motion, reverse its angle orincline from that shown in Fig. 1 to that shown in Fig. 2, and viceVersa.

Of course each of the seat-arms E is proor vertically-sliding block orplunger N, having inclined sides, as shown. This block N when in itsnormal position is sufficiently high for the lower end or tooth of thesegment J to strike it as it moves along the inside of the track K. Inoperation when the seat-back is swung from the position shown in Fig. 2to that shown in Fig. 1 the pin J,

with its head or segment J, travels along the slot K and is at the sametime gradually turned by the link I from the horizontal position shownin Fig. 2 to the'vertical position shown in Fig. 3, in which position itreaches the block N. As the pin passes over the block, slightlydepressing it,- the segment or head is turned in the opposite direction,thus allowing the back of the seat. to take the position shown in Fig.1, in which position the segment is at. right angles to that shown inFig. 3 and exactly opposite to that shown in Fig. 2.

The lower ends of the arms H are provided with theinwardly-projectinghorizontal extensions P, (see Figs. 5 and 6,) which are grooved on theiropposite sides at P and which are bolted at P to the opposite ends ofthe horizontal connecting-bar 0, so that the arms Hare practicallyconnected at their lower ends. At the opposite ends of the seat, beneathit, are sliding rockers S, which rest on the'curved or bent supports orways T, supported by the frame and provided with the flanges 'or guardsT. (See Figs. 1, 2, 5, and 7.) These rockers are engaged by theextensions P, which lie in the central open ing S, by means of thegrooves P, and are held therein by the projections S. U is theseat-frame, provided at opposite ends on its under side with the tenonsU, which fit in the grooves S on the upper surfaces of the rockers. Thusit will be seen that as the arms H swing or vibrate to move theseat-back F as the back is moved from one side to the opposite. side.The preferable shape of the surface of the ways J consists of ahorizontal center and inclined sides, as shown. Hence by means of thehandle H the seat-back and cushion are reversed with perfect ease andthe proper inclinations produced in both.

In the modification shown in Fig. 8 the rocker V is rigidly secured tothe seat-frame V and has a plain central groove V, so that the extensionP is not locked therein.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a car-seat, the combination of the frame, the seat-back, a slottedarm whose upper end is pivoted to the seat-back and which is pivotednear its lower end to the frame,

the seat arm provided with a horizontal grooved plate or track, and alink pivoted-at one end to the seat-back and provided at the other endwith a pin or projection extending through the slot in the said arm andinto the groove in said plate or track, whereby when the seat-back isswung from one side of-the seat to the other the angle or inclinationthereof is reversed, substantially as described.

2. The combination, with the frame, seatback, slotted arm H, pivoted tothe seat-back and the frame, and the link I, pivoted to.

the seat-back and provided with the pin or projection J, extendingthrough the slot in said arm and engaged by the track on the seat-arm,of the tooth-segment J on the end of said pin J, the seat-arm and trackthereon provided centrally with the chamber L, connecting with thegroove in the track, and the head or plunger N, whereby the saidtoothsegment is turned as it passes over said head or plunger,substantially as set forth.
